Postmates is an app-based courier service that's grown quite popular recently, and the company is expanding its reach to tech's two hottest hubs: Silicon Valley and Austin, TX. The Silicon Valley area includes Palo Alto, Menlo Park, Mountain View, and Atherton, if you're interested in the specifics.

Postmates is actually pretty neat, if kind of expensive. The company partners locally with restaurants, stores, and other retailers to build a "menu" of items available for purchase, which you then select in the app, and a Postmate courier then accepts your order and delivers said items to your door.

Looking for a lot of extra gee-bees on a budget for your smartphone or tablet? SanDisk's almost unnecessarily ginormous 128GB microSDXC card is on sale at both Best Buy and Amazon today for just $99.99 shipped.

Both sites do charge sales tax in most applicable states, so watch out for that, but otherwise this is the lowest price we've seen this 128GB at by a solid $20, making this a genuine article at a genuine discount.

There's a new tower defense game on Android seeking your eyeballs and your money. It's called Prime World: Defenders and you can play it on Android andFacebook today with full gameplay sync. Yeah, you might hate Facebook, but not everyone does.

On the surface this is a traditional tower defense game – all the usual upgradable towers and waves of creeps are present and accounted for. In addition to all that, however, there's a collectable card element to Prime World: Defenders.

Good things come to those who wait. Android users didn't get an official Wikipedia app until January 2012, and it was a relatively bare bones release at that. Over two years later, it's really starting to show its age, as those Gingerbread screenshots sitting on its Play Store page aren't impressing anyone. But now we see a new version of the Wikipedia Beta app that finally seems poised to give us the native experience we've been waiting for.

Holy crap, that was fast. According to a flood of tips we just received, at least some owners of Google Play Edition devices are now seeing updates to over-the-air Android 4.4.3. The latest incremental update to KitKat was just published yesterday - some Nexus devices don't even have it. At the time of writing (Tuesday afternoon US) we've been told that the Google Play Editions of the HTC One M7 (2013 model) and the Galaxy S4 are receiving over-the-air updates.

Google has just announced the official Project Tango tablet development kit, an insanely powerful slate powered by NVIDIA's Tegra K1 processor. This thing is beastly - 7" display (unknown type / resolution), 4GB of RAM, 128GB of storage, Tegra K1 quad-core processor (not the dual-core 64-bit Denver), motion-tracking cameras, integrated depth sensing, Android KitKat, and LTE. The big catch? It's only for developers, and it will cost $1024. Yikes. Granted, this is a high-tech, cutting-edge experimental product designed as a reference and development tool, not something to check your Gmail on while browsing Reddit.

The Pebble's software updates keep it slow and steady. Today's 2.2 firmware release doesn't rock the boat, but it introduces a few features that I'm sure fellow Pebble owners out there have wished for at some point or another. The first of which is the ability to reorder items in the launcher menu. Now if you hold the select button on an item in the menu, you can drop it somewhere else in the column.

Yesterday we brought attention to an issue with Motorola's international devices wherein the carrier ID would be displayed in the status bar all the time, making the notification area almost useless in many circumstances. Well, Motorola VP Punit Soni happened to notice the post and chimed in with an update – it turns out Motorola is rolling out a fix in 4.4.3.
